Christey" <coley@...us.mitre.org> CC: oss-security <oss-security@...ts.openwall.com>, Daniel Stenberg <daniel@...x.se> Subject: CVE Request -- cURL / mingw32-cURL -- Did not strip directory parts separated by backslashes, when downloading files Hello Steve, vendors, cURL upstream has released new curl / libcurl v7.21.2 addressing one security flaw, specific for operating systems, where backslashes are used to separate directories from file names. More details follow: cURL did not properly cut off directory parts from user provided file name to be downloaded on operating systems, where backslashes are used to separate directories and file names. This could allow remote servers to create or overwrite files via a Content-Disposition header that suggests a crafted filename, and possibly execute arbitrary code as a consequence of writing to a certain file in a user's home directory. Different vulnerability than CVE-2010-2251, CVE-2010-2252 and CVE-2010-2253. Note: As already mentioned in . This flaw only affected those operating systems, where backslash is used to separate directories and file names, thus Microsoft Windows, Novell Netware, MSDOS, OS/2 and Symbian to mention some of them.
